"He who knows not, and knows not that he knows not, is a fool - shun him.
He who knows not, and knows that he knows not, is a child - teach him.
He who knows, and knows not that he knows, is asleep - wake him.
He who knows, and knows that he knows, is a sage - follow him"
I prefer Maslow's four levels of competence ....
Unconscious Incompetence
Conscious Incompetence
Conscious Competence
Unconscious Competence
It's therefore entirely possible for a 20 000 hr ATPL to be as dangerous as a rookie.
I prefer to think that we all have an envelope in which we can operate safely and that a PPL can be just as safe as an ATPL, but only if they stay well within their envelope.
Oh - I also think that flying is as close to driving as sex is to love!
